Wondering how to check your iPhone battery health? Think you might need to replace your iPhone battery?
If you’ve had your phone for a couple of years, then your battery could be starting to degrade. This quick guide will show you how to find out if your iPhone needs a battery replacement.
How to Check iPhone Battery Health
There’s another way provided by Apple to figure out how your iPhone battery is doing. iOS 11.3 and newer versions bring a new Battery Health tool that lets you monitor the health of your battery.
- Open the Settings app on your iPhone.
- Choose Battery.
- Tap on Battery Health.
- The Battery Health screen will show you two important indicators of battery health: Maximum Capacity and Peak Performance Capability.
The Maximum Capacity means how in good health your battery is. All new iPhone and new iPhone batteries will have a maximum capacity of 100%.
As time goes by, the battery will take a beating and degrade, so its maximum capacity may reduce below 100%.
As you can see in the picture above, the maximum capacity of this iPhone’s battery is at 84%, which is still in good shape.
Here’s what Apple has to say about maximum capacity battery:
Maximum battery capacity measures the device battery capacity relative to when it was new. Batteries will start at 100% when first activated and will have lower capacity as the battery chemically ages which may result in fewer hours of usage between charges.
A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge.
The Peak Performance Capability section will let you know if anything is wrong with your iPhone’s battery.
For batteries in good shape, you may see “Your battery is currently supporting normal peak performance.”
If there’s any issue, you’ll probably see “Your battery health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity.”
